OAKLAND -- There were moments in Golden State's 97-87 overtime win against San Antonio in Game 4 of the Western Conference semifinals when the Warriors looked well on their way to a 3-1 series deficit.
Harrison Barnes and Jarrett Jack didn't let that happen.
The duo combined for 23 points after the third quarter as Golden State found a way to tie the series and ensure a return trip to Oracle Arena Thursday night for Game 6. Barnes scored a game- and career-high 26 points and Jack added 24.
"I'm not surprised by anything," Warriors coach Mark Jackson said. "One thing I know, this team will not lay down, this team will not quit. It looked dark. It looked awfully dark."
Game 5 will be Tuesday in San Antonio.
The Warriors played from behind for most of the game, but after Klay Thompson got to the rack to tie it at 84 with 30 seconds left, Golden State was in position to steal the win.
It nearly happened in regulation, but a 20-foot jumper from Jack missed at the buzzer -- Golden State's second would-be game-winner to miss this series.
Overtime belonged to the Warriors, who scored the period's first nine points to secure the franchise's first-ever postseason overtime win at home.
With Game 4 in the books, all attention turns to the sprained left ankle of Stephen Curry.
He gave it a go in Game 4, but could only do so much. Clearly hobbled by the injury he suffered late in Game 3, his opportunities were limited. He took an anti-inflammatory shot before the game -- his third of the playoffs -- and injected life into the largely disengaged crowd at Oracle Arena with 10 third-quarter points, but wasn't the usual consistent threat.
About an hour before tipoff, Jackson found Curry outside the arena chapel.
"Looked at Steph and had a conversation with him," Jackson said. "He said, 'I'm going to give you what I got, Coach.'
Immediately, Jackson was concerned.
"That's not the language (Curry) speaks," he said. "I knew right away that he was not 100 percent."
After discussing the matter with general manager Bob Myers, it was decided: Curry would play.
Despite his obvious limitations, Curry still managed to score 22 points in 38 minutes on 7-of-15 shooting.
"I was conscious of it. I didn't want to start-stop too quick or change directions too quick," Curry said. "I didn't really do too much shifting, but I was still able to find some open looks. A couple times in overtime I drove the paint, but still didn't have my full thrust. Looking back, I probably shouldn't have done that."
Manu Ginobili scored 21 points to lead the Spurs, but did so on an 8-of-18 effort from the field. San Antonio shot just 35.5 percent from the field (33-for-93), but that was only marginally worse than Golden State (35-for-92, 38 percent).
"It's not frustrating, but what's disappointing is we had a great game, we had them where we wanted," Ginobili said. "We blew it. So it kind of hurts. But, you know what, we are 2-2. We're going back home. We have a great opportunity to go back up in the round, in the series."
The late-arriving crowd at Oracle didn't miss much as the game opened with one of the more sloppy quarters of the playoffs.
After a pair of Curry threes made it 11-6 Golden State, San Antonio countered with a 14-0 run over the next seven minutes. The Warriors didn't score on 17 consecutive possessions before Barnes stopped the bleeding with an inside bucket at the 1:49 mark of the quarter.
Barnes scored the final eight points for Golden State, which trailed 26-19 at the end of the quarter, punctuated by a corner three from Ginobili with 0.5 seconds left.
Despite not taking a shot for the final 17 minutes of the first half, Curry was still Golden State's third-leading scorer (6) at halftime when San Antonio led 45-37. It was the second-lowest first-half output of the season for the Warriors.
If Curry's ankle injury wasn't too much to overcome, Andrew Bogut picked up three fouls less than six minutes into the game and spent the rest of the half on the bench. His replacement, Festus Ezeli, committed four first-half fouls of his own.
The answer? Andris Beidrins.
Biedrins, the lone holdover from the "We Believe" playoff team in 2006-07, entered to a loud ovation and logged three first-half minutes -- his first playing time of the postseason. He wasn't the only non-rotation player to see court time as Richard Jefferson was forced into five minutes with Curry hobbled.
David Lee also saw his most extended playing time since tearing his hip flexor against Denver in Game 1 of the first round. He finished with five rebounds in eight minutes and was 0-for-2 from the floor.
-The Warriors are 3-3 all-time on Mother's Day.
- It was the first Warriors playoff win since 1975 that came with the team shooting under 40 percent.
- No one on the Spurs had more the three assists. No one on the Warriors had more than four.
- Golden State won the rebounding battle 65-51. It has out rebounded the Spurs in every game this series.
- With 19 points and 15 rebounds, Tim Duncan tied Shaquille O'Neal for the third-most playoff career double-doubles.
